IMPROVEMENT IN CCOKING-STOVES.

Specification forming part of Letters Patent No. 125,367, dated April 2,1872.

Be it known that I, ARCHIBALD WIETING, of Fort Plain, county ofMontgomery, State of New York, have invented a new and ImprovedCooking-Stove; and I declare the following to be a full, clear, andexact description of saine, such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawing which forms a part of this specification.

My invention relates to certain improvements in that class of stovesknown as self-feeding stoves 5 and my invention consists-first, ofimprovements in the feeder; second, of improvements in the fire-pot;third, of improvements in the grate; fourth, the arrangement of collarat the top of the pot; fifth, of a device for changing the position ofthe pot-holes in the upper plate.

In the drawing, Figure 1 is an isometric projection of a stove with thelids removed. A is the feeder, reduced in size at a a, provided with lida. B is the nre-pot, circular at bottom and oblong .at the top. Y b is acollar which prevents the fuel from burning when it is not utilized, andserves to drive the heat forward. C is the grate. D is a damper to closeoff the draught into the top of the exit-flue, and thence into pipe p. dare dampers in descending flues on both sides of the stove adjacent tothe' exitflue. Fig. 2 is a section by a plane along the line R R, inwhich A is the feeder, reduced at a a; lid, ct; fire-pot, B; collar, bgrate, C ash-box, g exit-flue and pipe-hole,pp damper, D 5 andhorizontal fine, f. Fig. 3 is a section along line P P and Q Q', showingkettlehole e in top plate c ef; damper d in descending-flue F 5 bottomhorizontal flue f. Fig. 4is section ou line P Q, in which similarletters represent similar parts. Fig. 5 is section along the plane ofthe top of the fire-pot. Fig. 6 is a section along P Q, showing ovens O0,1reboX, grate, ash-box, and horizontal connectingflue j. Fig. 7 is asection on plane of hearth, showing the arrangement of the horizontallines. Fig. 9 shows a device for changing the positions of thekettle-holes by means of the movable pieces y z.

First, I propose to make the feeder A similar in general shape to aboot-leg, large at the top, reduced in size at et a near the bottom, so

as to be out of the way in cooking, and to provide a lid or lids, a', atthe top, to close off all draught through the fuel in the feeder andthus prevent its ignition. I pitch the lower end of the feeder forward,making its back surface to be the continuation of the back of thefire-pot against which it rests, and to correspond laterally incurvature with the top of this part of the pot, so that the fuel in thefeeder will be sure to replace that which is consumed at the base of itscolumn. I terminate the bottom of the feederinacircle, ellipse,

or other suitable form.

Second, I make the pot elliptical or oblong at the top, in order to givesufficient room for the fuel to burn in front of the feeder A and yeteconomize space in the stove or range, presenting, at the same time, thegreatest radiating surface to the ovens at its sides. I make itgradually smaller from the top downward, terminating it at the bottom ina circle where the grate is located, making the linear elementsextending from top to bottom either curved or straight. This serves tocarry all slate, cinders, and ashes onto the grate beneath the pressureof the feeding-column. I lay stress upon the peculiar shape of the pot,being, in connection with the feeder, the form best adapted to insurecertainty of feeding itself, and economy of fuel, heat, and space.

Third, the grate is made thus, viz.: The outside ring S, the solidbutton t iu its center, and the bar connecting the two, are cast in onepiece; and at the front end of this bar is a projection downward,provided with a hole to receive the poker in shaking the grate. Themiddle ring s is cast separately, as is also the bar, which, extendingbeyond the largerin g at both ends, sets into receptacles and supportsthe grate. In putting this grate together the separate bar is placedbeneath the large ring and button, perpendicular to their connectingbar.The second or middle ring sis then placed on top and the two rmlyriveted together, bringing the top surfaces of the rings and button intothe same horizontal plane. The crosssections of each of the rings and ofthe button are triangular, as shown, presenting a flat surface downward.The upper surfaces are all roughly serrated, so that when a poker isinserted in the hole and shaken sidewise the t uter movable ring and theinner movable button breakup and crush any cinders or slate by raspingthe substance against the middle sta tionary ring. In a large grate,instead of serrating the inner surface of the outer ring, I propose tocast ribs upon it, which, projecting downward and toward the middlering, serves the same purpose, and admits of the draught coming upthrough from below. If necessary, I form the middle ring and button inlike manner.

I know that a grate has been made with rings and buttonmoving in asimilar manner, but possessing different relative positions, and inwhich the middle ring presents but one rasping surface, which is on thesame conical snrface with that of the button 5 therefore,I do not claimbroadly the use of the outer movable ring and middle stationary ringwith the movable button, but limit myself to the device shown anddescribed.

In attaching the f'eeder A to a stove or range I do not propose to limitmyself to the shape or size of its top, but to vary it so as to suit thestoves and ranges now in use. I extend the top of the back portion ofthe fire-pot up to the top plate of the stove, carrying` this extendedportion around to the sides of the feedy ing-column. This serves toprevent the fuel from burning behind the column, where it is notutilized, and dri\ es the heat forward and around over the ovens. Ipropose sometimes to dispense with this extension, and place, instead, acollar, b, extending from the top of the pot to the top plate of thestove, to serve the same purpose. When it is desired to change thepositions of the kettle-holes I effect'it, as shown in Fig. 9, by simplytransposing the two pieces y and z. rlliese pieces are each rectangular,and the piece y carries the kettleholes with it. By removing the piece zthe Acarrier y can be slid or shifted into its place,

and the piece z transferred to the other end of the carrier.

Having thus described my invention7 what I claim as new, and desire tosecure by Letters Patent, is-

l. In a stove or range, the combination of the feeding device A,fire-pot B, grate C, and collar b, when the same are constructed andarranged and operate substantiall yin the manner set forth.

2. The collar b, situated and operating as described.

3. The rectangular carrier-piece y with removable pieces, as shown, andrectangular removable piece z for changing the position of thekettle-holes, operating in the manner substantially as shown anddescribed.
